I've just finished tiling my Bathroom walls and whenever I've grouted in the past, I never seem to be able to achieve a satisfactory smooth finish to the grout. Has anyone any suggestions on the following:- 1) How best to apply the grout 2) How to achieve a smooth finish to the surface 3) How long to leave it before wiping off any excess. Should the excess grout be wiped off the tiles immediately or left to dry and then wipe it off with say warm water 4) What's the most appropriate grout to use in a Bathroom, which has a shower over the bath 5) I've tiled about 15 square metres of wall and the joints are 2mm thick. What size tub of grout would I need to complete the grouting Alternatively, if someone could post a step by step guide to successful grouting then this would be very much appreciated. Many thanks.
